Title:
PREPARATION METHOD FOR GRAPHENE OXIDE FIBER, AND FIBER OBTAINED THEREBY
Document Type and Number:
WIPO Patent Application WO/2020/221361
Kind Code:
A1
Abstract:
Disclosed in the present invention are a preparation method for a graphene oxide fiber, and fiber obtained thereby. A polyelectrolyte is prepared into a spinning stock solution by means of a wet spinning method, graphene oxide is added in a coagulation tank to serve as a coagulation bath, the spinning stock solution is injected into the coagulation bath, a diffusion reaction is carried out, and winding, washing and drying are carried out to obtain the graphene oxide fiber; the preparation method has the advantages that equipment is simple, the costs are low, the spinnability is good, and the method is suitable for large-scale production; moreover, the prepared fiber has multiple layers of fiber walls; the fiber has good tensile strength and a super-high specific surface area and is widely applied to the fields of catalysis, adsorption, flexible sensors, thermal preservation and insulation materials and tissue engineering.
